My primary research interests are currently focused on PUIs,
Perceptive User Interfaces, in pen computing with particular emphasis on sketch
recognition and the application of pattern recognition to user's actions.

I also
work with Microsoft's Bay Area Research Center on small components of the
MyLifeBits project. My specific project in this area involves browsing in large,
time-varying data sets.

Finally, I do some work in Bioinformatics, specifically
on the design and implementation of a community-based repository for
biological multimedia information with applications to research and to
teaching, and the design of software tools to aid field biologists in data collection.
